Chinese Orchestra Full Edition

Good plugin, but I get a weird distortion sound that entirely distorts the instrument sometimes and I don't know how to get rid of, does anyone know? Thank you.

This could be an audio buffer issue; I have heard of a similar problem affecting several other commercial plugins such as The Loki Bass by Solemn Tones. If your DAW has the option, try enabling "Use fixed size buffers" for the VST (in FL Studio this can be found on the "PROCESSING" tab in the wrapper settings). You can also try increasing the audio buffer size (increasing the number of samples will add latency, but can reduce glitches).
